RESETTING THE LAMP CHANGE TIMER
The lamp change reminder timer is reset by disconnecting the UV power source from the AC supply, waiting for at least fifteen seconds and then reconnecting to the AC supply with the timer button depressed. The UV power source will emit a solid three-second beep and show the word reset on the led display indicating that the reset was successful.
Note; The electrical cap from the ballast was updated in early 2014. If you have the older style connector pull out the metal “C” ring on the cap before removing cap by pulling away from UV housing. When re installing the old cap, make sure “C” ring is pulled out before attempting to put cap back into place.
